Strange 1.3 kilometers Wide Asteroid Caught on Radar as It Zooms by Earth

Dubbed 2014-JO25, the asteroid came nearest at 12.20 GMT and is now hurtling away from the centre of our solar system, said Ian Carnelli, an astronomer from the European Space Agency (ESA).

The Arecibo observatory in Puerto Rico—which has one of the world's biggest radio telescopes—captured the 2014 JO25's first images, showing a “dragon-shaped” object that is likely "two large asteroids that fused together".

You may not see them, but space rocks whizz above our heads all the time. But large asteroids passing this close to Earth remain a rarity.

The next one will pass by in 2027, a 800-metre long object that will come within one Earth-to-the-Moon distance.

The last time 2014-JO25 was in our vicinity was 400 years ago, and its next close encounter with Earth won't happen until sometime after 2600.
